4 Claims. (Cl. 22B-15)` This invention relates generally to boxes andmore particularly to reinforcing means located therein.

One of the primary advantages of my invention resides in the simplifiedform of reiniorcing,

5 this preventing crushing of the carton or box.

Another primary advantage of my invention resides in the diagonalpositioning of the reinforcing, such receiving the contents of the boxtherebetween whereby the pressure against the l several sides of the boxis reduced and consequently bulging of .the box is prevented.

A third primary advantage resides in the positioning of the reinforcingpartitions at the several corners of the box whereby leakage from l thecorners is prevented as will be later described.

Another advantage lies in the placing of openings through thereinforcing means whereby the contents of the box may flow'from one partof the box to thel adjacent portions thereof.

Still another advantage resides in the construction of the partitions,these being identical in character whereby they are not only easilymanufactured but they are also easy to insert in their positions in thebox.

Other advantages will become apparent as the description proceeds.

In the drawing:-

Fig. 1 is a perspective View of a box or carton having my improvedreinforcing means therein.

Fig. 2 is a cross sectional view taken along the line 2-2 of Fig. 1.

Fig. 3 is a diagrammatic view illustrating the method of manufacturingthe reinforcing partitions from a single length of material, preferablycorrugated cardboard.

Fig. 4 is a perspective View showing how the partition closes any corneropening in the box.

Similar numerals refer to similar parts throughout the several views.

Referring to Fig. 1, numerals 1 and 2 indicate the ends of a box havingsides 3 and 4. As clearly shown in Fig. 1, the end 1 has an upper flap 5and a lower flap 6 and the end 2 has an upper flap 7 and a lower flap 8.The

upper flaps 5 and 7 are shown as extending outwardly while the lowernaps 6 and 8 extend toward one another to form the bottom of the box.

'As shown in Fig. 2, the side 3 of the box has an upper flap 9 and alower iiap 10 while the side 4 has an upper flap 11 and a lower iiap 12.

Referring now to Fig. 3, numerals 13 indicate the reinforcingpartitions, these being die cut from a single piece of material andbeing formed with end members 14 which have a vheight substantiallyequal to the depth of the box. YAlso,A a central portion 15, having aslot 16y therein, is formed as shown and these partitions 13 are adaptedto be interlocked together as clearly shown inA Fig. 1, the openings 19being in stag-` gered or reverse position asv shown. Thus, there willalways be two openings 19 in reverse fashion to the other two openings19 whereby the contents .of the box,`which may be bulk starch or thelike, can `be expediently yflowed into the box lduring the fillingprocess but yet which will be held from excessive lateral movemnt duringthe yshipment Iof the box. Also, the end portions 14 of thetwo'partitions come against the interior corners of the box, see Fig. 4,to prevent the leakage of any of the bulk material from the box.v y E Inusejtlie box is loaded with bulk material, such as "starch, bulk candy,and thelike, by means of a spout, if desired, which spout'is moved aboutabove the upper open end of the box until the box is level full. Inregard to the ease of iilling it will be noted that the two interlockedpartitions really only divide the box into two separate bins inasmuch asone of the partitions is cut away along its upper edge as is clearlyshown in Fig. 1 of the drawing.

Also, along this same line, it is to be noted that the other partitionis cut away at the greater portion of its lower edge whereby the bulkmaterial may be easily distributed throughout the box. The cut awayparts of the partitions, it will be realized, materially aid in the easyloading of the box because they permit the bulk material to roll or iiowlaterally under the influence of gravity.

However, it is desired to clearly bring out the fact that applicant doesnot sacrice one of the main purposes of the partitions by his inclusionof the openings in the partitions. That is, the partitions stillfunction to increase the strength of the box and this is very necessaryas the boxes are stacked one upon the other until the lower boxes mayycarry a dead weight of perhaps a ton. This strength of the box isattained not only when the box is completely full of the bulk materialbut also when the bulk material has settled the usual amount, say, 10percent. This desideratum is a very important one because this settlingalways occurs due to several facts, not recited, and thusthe upper partof the box is empty. If applicants strengthening partitions were notused, the 55 weight of the upper boxes upon those beneath would causethe latter to be bulged outwardly and distorted from shape with aconsequent breakage of the boxes and leakage of material therefrom.

In applicants improved box, it will be noted that the settling of thebulk material; does not reach below the openings in that partition whichhas its openings faced downwardly and consequently this partition isbuttressed and held in place by the bulk material on each side thereofand also the bulk material which ows underneath the upper edges 19 ofthe cut away portions. Thus, even though the bulk material has settledits full amount,` nevertheless the one partition will have its completeupper edge rmly held and supported in position against lateral movementand the other partition will likewise furnish a very substantialsupporting means whereby theboxes created by applicant are indeed verymuchsuperior to those now utilized.

The diagonal partitions also serve to break up the load within the boxand when the boxes are being handled the shifting of the load therein isdivided into a number of components inasmuch as the partitions act inthe nature of baille plates and this preyents excessive impacts of thebulk material against a single wall of the carton .orboishy .Having thusrevealed this invention, I claim as new and desire to secure thefollowing combinations and elements, or equivalents thereof, by LettersPatent of the United States:

1. In combination, a paper box adapted to contain bulk starch or thelike, and reinforcing means wtherefor, saidl yreinforcing meanscomprsing two diagonally located partition members, each of said membershaving a relatively large opening therethrough, each yopening beingstaggered with respect to adjacent openings for the purpose described.

2. In a box havingfour sides located substantially in rectangularrelation, each side having a flap adapted to be folded towards the othersides to substantially the same plane as the other naps, the combinationof, two partitions crossing each other, the opposite edges of thepartitions snugly engaging the respective corners of the box to preventleakage and the flaps engaging against the partitions.

3. In combination, a paper box having a reinforcing structure diagonallylocated therein, said reinforcing structure comprising a member havingtwo end portions of substantially the same height as the depth of thebox to which it is applied and a central portion having aslot extendingsubstantially half way?A therethrough, said kmember being cut awaybetween said ends and central portion to form relatively large openingswhereby the contents of the box may flow therethrough and asecond memberhaving means interlocked with the said slot, said second member havingrelatively large openings, the openings in one of said membersterminating iiush with one side of the box and the openings in theotherof said members terminating flush with the opposite side of thebox.

4. In combination, a rectangularly shaped carton having a horizontalbottom, vertical partitionscrossing each other and extending into thekseveral vcorners of the box, said 'partitions being substantially equalin height to thevertical dimension of the box, one of said partitionsbeing cut away from its bottom edge at each side of its point ofAcrossing the other partition, these cut away portions terminating at avpoint not higher than three quarters of the vertical dimension of thecarton for the purpose described and the other partition being.similarly` cut away but in reversed fashion.
